### 3.2 Lease Versions
- **Lease V1**: Basic lease support (SMB 3.0)
- **Lease V2**: Adds epoch support for better consistency (SMB 3.0.2+)

## 4. Data Structures

### 4.1 Lease Key Structure
```java
package jcifs.internal.smb2.lease;

import java.security.SecureRandom;
import java.util.Arrays;

public class Smb2LeaseKey {
    private final byte[] key;  // 16-byte lease key

    RECURSIVE_TREE,        // Entire subtree (if supported)
    METADATA_ONLY,         // File attributes but not content
    FULL_ENUMERATION      // Complete directory listing
}

### Types génériques avec des paramètres de types

Il existe certaines structures de données qui contiennent d'autres valeurs, comme `dict`, `list`, `set` et `tuple`. Et les valeurs internes peuvent elles aussi avoir leurs propres types.
